Problems solved by technology

Because the starch is powdery and the particles are very fine, it is not easy to mix evenly, and it is easy to produce fish-eye-shaped insoluble agglomerates
The existing improved method is to add bulking agent and other additives to make expanded starch granules, or add surfactants, bulking agents and other auxiliary materials to spray dry and granulate. The preparation process is complicated and other bulking agents need to be added.

Embodiment 1

[0018] A method for preparing starch granules, characterized in that it may further comprise the steps:

[0019] 1) Take 5kg of potato starch, 1kg of water, and 0.5kg of maltodextrin and mix well to prepare a mixed material;

[0020] 2) Put the above mixed material into the wet granulator to granulate to obtain starch wet granules, set a microwave treatment section at the outlet section of the wet granulator, and adjust the microwave power to 1000 watts / kg for the starch wet granules running in the microwave effect section , the time for the wet starch granules to pass through the microwave effect section is 40s, and then the wet starch granules enter the drying equipment to obtain dry starch granules with a particle size of 10-100 mesh and a bulk density of 1.05-1.15g / cm 3 .

Embodiment 2

[0022] A method for preparing starch granules, characterized in that it may further comprise the steps:

[0023] 1) Take 10kg of tapioca starch, 3.5kg of water, 1.5kg of sucrose, add 1.4kg of green tea powder, and mix well;

[0024] 2) Put the above mixed material into the wet granulator to granulate to obtain starch wet granules, set a microwave treatment section at the outlet section of the wet granulator, and adjust the microwave power to 3000 watts / kg for the starch wet granules running in the microwave effect section , the time for the wet starch granules to pass through the microwave effect section is 5s, and then the wet starch granules enter the drying equipment to obtain dry starch granules with a particle size of 10-100 mesh and a bulk density of 1.05-1.15g / cm 3 .

Embodiment 3

[0025] Embodiment 3: a kind of method for preparing starch granules is characterized in that comprising the following steps:

Abstract

The invention provides a method for preparing starch granules, which comprises the following steps: 1) uniformly mixing starch, water and an adhesive according to the weight ratio of 50-100:10-45:5-60 to prepare a mixed material; 2) adding the above mixed material in a wet type granulator to obtain starch granules, passing the starch granules through a microwave treatment section provided at an outlet of the wet type granulator, entering into a drying device to obtain the starch granules, wherein the granularity is 10-100 meshes and the packaging density is 1.05-1.15g / cm<3>. The method for preparing the starch granules is characterized in that the starch is prepared to starch granules, a process of microwave treatment is added after wet type granulation, the microwave heat-effect and microwave non-thermal effect can be enhanced so that the starch granules absorb microwave electromagnetic energy to generate collision, crushing and aggregation effects, the pulverization rate of starch granules can be reduced, and the uniform gelatinization effect of the starch granules can be enhanced. The provided method has the advantages of simple process, convenient operation, less investment and high efficiency, and the produced starch granules have the convenient eating and good mouthfeel.

Description

technical field [0001] The invention belongs to the field of food processing, in particular to a method for preparing starch granules. Background technique [0002] Starch is a high polymer of glucose and can be eaten. Since starch is insoluble in water, it can gelatinize into a colloidal solution when heated to about 60°C with water. Usually, when people eat starch paste, they first mix it with a small amount of clear water to make starch paste, and then use boiling water to brew the starch into a paste and eat it. Because the starch is powdery and the particles are very fine, it is not easy to brew evenly, and it is easy to produce fish-eye-shaped insoluble agglomerates. The existing improved method is to add additives such as bulking agent to make expanded starch granules, or add auxiliary materials such as surfactant and bulking agent to spray dry and granulate. The preparation process is complicated and other bulking agents need to be added. Contents of the invention...
